Replace an Xml attribute/element value via Java

**j_kathiresan** · 05-12-2011, 04:10 PM

Hi,

I've the XML content as String. I need to search for a name (which can be an attribute name or element name) and need to replace the value of it.

Currently i'm using regular expression to find the tag and replacing it. The problem is it is taking more time.

Even the XPATH api takes more time to process and set the value.

I thought of using SAX parser but not sure how to set the value.

Can anyone please help me on this?

Thanks,
Kathir

As far as I understand it, SAX is an API for XML parsing, not for XML writing. Anyone, please correct me if this is wrong.

I don't know. If you're only changing the text in some nodes, then perhaps you can do this with SAX, either writing the unchanged text as it's read in, or writing out the changed text if the appropriate node is identified. But I don't think it would be easy to change the structure of the XML via SAX.

But a warning: I'm no XML expert.
